WebJun 3, 2016 · Some good answers below, but I'll add that if somehow you had lithium, you would know it. It not only reacts with water, but floats on the surface due to its lower density. The rate of reaction, far less reactive than sodium or potassium. Hydrogen is evolved in the reaction, but usually not enough heat to ignite it into flame. WebDrop a small piece of Li, Na or K into each dish. The metal will scoot around on the surface of the water, producing bubbles of hydrogen and causing the phenolphthalein indicator to turn pink. Optional: Use hexane to rinse mineral oil from metal surface. This produces a faster reaction. Be careful of larger chunks, which, due to internal air ...
